PURPOSE: To realize water making and air-conditioning efficiently by a system wherein a water making unit and an air conditioner are organically combined in balanced shapes.

CONSTITUTION: Dried air, whose temperature previously rises, discharged from a water making unit 1 heat-exchanged by a heat exchanger 2 with the outside air, and the air is further cooled by an evaporating cooling device 3. The cooled air is let pass through a heat exchanger 4 to cool indoor air. Air exhausted from the heat exchanger 4 is returned to the water making unit 5 by a circulation course 5. Water produced by the water making unit 1 is stored in a water tank 7, and the water is forwarded to a facility 8 for a drink, etc. and utilized. Water, which is reutilized and disposed, is used for a water closet, a bath, etc. 9. Thus, an energy conserving type water making and airconditioning system can be obtained.
